    This sample shows a "fishbone" layout of a tree model of cause-and-effect relationships.
    This type of layout is often seen in root cause analysis, or RCA.
    The layout is defined in its own file, as <a href="FishboneLayout.js">FishboneLayout.js</a>.
    When using FishboneLayout the diagram uses FishboneLink in order to get custom routing for the links.
